Photo: a maxillary premolar area appears very DARK on the buccal aspect. Most likely?
Show answer and explanation
Correct answer: A. Old amalgam restoration (showing through / amalgam discoloration)
- A. Correct. The dark grayish appearance is classic for an old amalgam restoration darkening the tooth/showing through enamel (or amalgam staining), as seen in the image.
- B. Incorrect. A vascular lesion is a soft-tissue red/blue blanchable lesion, not a discolored tooth.
- C. Incorrect. A varix is a dilated vein (e.g., ventral tongue/lip), not a discolored tooth surface.
